UPSTREAM: drm/rockchip: Optimization vop mode set

Rk3288 vop timing registers is immediately register, when configure
timing on display active time, will cause tearing. use dclk reset is
not a good idea to avoid this tearing. we can avoid tearing by using
standby register.

Vop standby register will take effect at end of current frame, and
go back to work immediately when exit standby.

So we can use standby register to protect this context.

phy: rockchip-emmc: fix compile issue on arm64 platform

This patch rename "reg" property to "reg_offset".
We rename it to fix the compile issue on ARM64 platform:
(reg_format): "reg" property in /phy has invalid length (4 bytes)
(#address-cells == 2, #size-cells == 2)

This's because "reg" is very special one which should keep the
*-cells with its parent node and can't be overwrited even if we
do that explicitly. On 32-bit plafform, the default *-cells
fit for what we assign to "reg". But that's not correct for 64-bit
platform. So we can see two possible solutions to fix this problem:
A) make phy-rockchip-emmc as a child phy node and overwrite its
parent's #address-cells and #size-cells.
B) avoid using this special property.

we use it just for passing on a offset for different Socs, and there's
no requirement to change the code to make phy-rockchip-emmc as a child
node. so choose option B) is sane.

UPSTREAM: clk: rockchip: only enter pll slow-mode directly before reboots on rk3288

As commit 1d33929e2a2b ("clk: rockchip: switch PLLs to slow mode before
reboot for rk3288") states, switching the PLLs to slow-mode is only
necessary when rebooting using the soft-reset done through the CRU.

The dwc2 controllers used create really big number of interrupts in
special constellations involving usb-hubs and their number is so high,
it can even overwhelm the interrupt handler if the cpu-speed os to low.

Right now the PLLs are put into slow-mode in a shutdown syscore_ops
callback which means it happens on all reboots (not only the soft-reset
ones) and even on poweroff actions.

This can result in the system not powering off and getting stuck instead,
so we should move the slow-mode change nearer to the actual reboot action.

For this we introduce the possiblity to also set a callback that gets
called from the restart-handler directly prior to restarting the system
and move the shutdown-callback to this new option.

With this the slow-mode switch is done only on the necessary reboots
and also has a smaller possibility of causing artifacts.

UPSTREAM: clk: rockchip: switch PLLs to slow mode before reboot for rk3288

We've been seeing some crashes at reboot test on rk3288-based systems,
which boards have not reset pin connected to NPOR, they reboot by
setting 0xfdb9 to RK3288_GLB_SRST_FST register. If the APLL works in
a high frequency mode, some IPs might hang during soft reset.
It appears that we can fix the problem by switching to slow mode before
reboot, just like what we did before suspend.
